Actually, after a bit of research online march seems to make the best high magnification ffp scopes( prefer ffp over sfp), but I have no idea where I could buy one. I saw some reviews by a guy who had one on a .50 and he seemed happy with it. Also, about how much are march scopes? Like I said, money isn't really an object but I cant find a price listing anywhere. The 5-40x56 ffp seems like it would have a good magnification range for a .50
